Hierarchical components of human-computer systems

Abstract

This paper describes the hierarchical components of humancomputer systems (HCS). We will discuss the development and utilization of three packages for the IBM PC: a decision support system (DSS) called ’COMBI’ for multicriteria ranking, a hierarchical hypertext system called ’HHS’ for multicriteria evaluation, and a DSS for hierarchical design, called ’SED’. The study is based on an analysis of HCS components (information, user, and techniques) and major operations (development, representation, correction, learning and using).
